Causes of Hot Jupiter Inflation from Causal Discovery
Zehao Jin, Mohamad Ali-Dib, Yujia Zheng +3
Hot Jupiters often have radii larger than predicted by standard cooling--contraction models, but it remains unclear which process supplies or preserves the extra internal heat. We…
Clustering SPH Debris into N-body Fragments: A Collisional Code for Planet Formation
Samuele Crespi, Mohamad Ali-Dib, Ian Dobbs-Dixon
Giant impacts among planetary embryos generate long-lived debris that feeds back on late-stage terrestrial planet growth, yet most N-body models either assume perfect merging or tr…
Binary Star Evolution Modules in REBOUNDx
Mohamad Ali-Dib
Close-binary evolution couples Roche-lobe overflow (RLOF), common-envelope (CE) drag, stellar winds, magnetic braking, and gravitational-wave losses, exchanging mass and angular mo…
Causal evidence for the primordiality of colours in trans-Neptunian objects
Benjamin L. Davis, Mohamad Ali-Dib, Yujia Zheng +3
The origins of the colours of Trans-Neptunian Objects (TNOs) represent a crucial unresolved question, central to understanding the history of our Solar System. Recent observational…

Gravity-Bench-v1: A Benchmark on Gravitational Physics Discovery for Agents
Nolan Koblischke, Hyunseok Jang, Kristen Menou +1
Modern science emerged from reasoning over repeatedly-observed planetary motions. We present Gravity-Bench-v1, an environment-based benchmark that challenges AI agents on tasks tha…
